Background firstly, 
EMMC and NAND has the same clock control register named 'SD_EMMC_CLOCK' which is
defined in EMMC port internally. bit0~5 of 'SD_EMMC_CLOCK' is the divider and
bit6~7 is the mux for fix pll and xtal.
Previously a common MMC sub clock framework is implemented and shared by EMMC and
NAND, but that is coupling the EMMC and NAND, although EMMC and NAND is mutually
exclusive. see the link:
[https://lore.kernel.org/all/1jy23226sa.fsf@starbuckisacylon.baylibre.com/]
Now we plan to abandon common mmc sub clock framework and recovery the series.

Changes since v1 [2]
 - use clk_parent_data instead of parent_names
 - define a reg resource instead of sd_emmc_c_clkc
